 ### Seismic DDMS Change Tier - Preview
 Azure Data Manager for Energy now supports changing the storage tier of seismic datasets as a preview feature. You can move datasets between **Hot**, **Cool**, and **Cold** storage tiers based on access frequency, helping you reduce storage costs for historical or infrequently accessed data while keeping active datasets performant. This feature is available on request. To enable it, raise a support request in the Azure portal. For more information, see [Tutorial: Change the storage tier of seismic datasets](tutorial-seismic-change-tier.md).
